Especially after a good belly rub, a dog can bump into it Nose In her human as a way to say thank you. Mostly, this snoot boop feels cold and wet. The owner will be surprised: is it normal for a dog’s nose to look like this?
The answer is yes, that’s normal. “Even after snoozing, there is a hot nose,” said Anna Bilint, a researcher who studies animal behavior at Atvas Lorend University in Budapest, Hungary. “When a dog is asleep, their nose usually gets hot, and it dries out,” she told live science. After that, the dog wakes up, lets his nose lick, and he comes back to the cold.
But why are dogs’ noses cold, and can there be any benefit?

One idea is that a dog’s cold nose can help a furry animal control its body temperature. The nose help is so small, it is unable to make a meaningful contribution to the dog’s overall thermal regulation, Bint said.
To investigate further, an international team of scientists measured this Nasal temperature in many animals, Including horse, dog and mouse. By the time Bulint joined the project, the team had already learned that the tip tips of dogs and carnivores, or rhinos, are generally cooler than vegetarian plants. Presumably, the researchers thought, the help of a cold nose could be beneficial in the wild.
The team conducted two experiments – one focusing on behavior and the other on the brain – to see if cold rhenium could do a good job of investigating heat. In the first experiment, the team successfully trained three pet dogs to choose a hot object, about the same temperature as a potential prey, on an object object at room temperature. The results suggest that dogs can detect weak thermal radiation from a distance similar to prey.
In another, brain-centered investigation, scientists introduced a box of hot water and an insulating door that trained 13 pet dogs to stay still working. MRI scanner. When the insulating door was open, the response of the dogs’ brains was revealed when exposing the warm surface compared to the neutral. The region illuminating MRI was located only in the left hemisphere. This side of the brain is of interest to scientists because it processes responses to food, which in turn is linked to predatory activity in many spines, Blint said. He said that the specific region of burning in dogs – known as the somatosensory association cortex – helps bring together different sensations such as vision, body position and warmth. These parts of the brain combine these sensations together to plan action towards a goal such as targeting a goal object.
Given that this left neural region burns when the nasal tip comes to a hot surface, it is possible that dogs and possibly other cold-nosed animals may use the heat detection sense along with other senses in their ‘hunting toolbox’. ‘When they are looking for prey, the researchers said.
A recent study, however, is published in the journal February 2020 Scientific reportsThe case on a cold nose is too small to close firmly, Blint said, adding that a cold nose can be more sensitive to temperature differences. “People think canines follow their disgust [sense of smell], Which is probably really true. “But wind conditions or stormy weather can make it difficult for a working dog to follow the scent,” Blint said. Heat signals can help them. “
So, why is the dog’s nose cold? Bintlint and his team continue to find answers to this question. Now, they are wondering from what distance this type of heat probe can be useful. For now, only the dog knows the nose.
